Lette/rs Patent No'. 101,830, dated April 12, 1870.

The Schedule referred to in these Letters Patent and making part cf` thesame.

To all whom it may concern Be it known that I, SAMUEL CnUMr, of thecity, county, and State of New York, have invented a new and usefulImprovement iu Bronze-collecting Attach-- mentsto Bronzing-Machines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing forming part of thisspecification, and in which- Figures l and 2 represent outsideelevations at right angles to each other ot' my improvement as appliedto a'bronzing-machine; and

Figure 3, a sectional elevation of the saine.

Similar letters oi' reference indicate correspond-ing parts.

1n machines for bronzing labels, show-cards, and

' other work, the bronze being in the condition ot' an exceedingly tinepowder, becomes scattered, and tioating in the air, is not only lost toa large extent, but, being inhaled by' the worlnnen in attendance, isvery detrimental to health.

The vibration, consequent upon the'rapid working ofthe machine, as inthe case of a cylinder machine, towhich the invention is here shownapplied, although itis equally applicable to others, agitates andassists in scattering the bronze, so that, notwithstanding the machineis usually boxed in, to catch, in a drawer or receptacle below, thesurplus bronze brushcd olf the printed mattei' in its way through themachine and otherwise settling therein, a large amount of bronze#invariably escapes both through the necessary openings in the case andjoints or seams therein.

To obviate this loss and injurious escape of' the bronze, I attachto'the brouzing-ulachine or case, in which tlze same is boxed, what Idenon'xinate avacuum bronze-collector, and which consists of asuction-fan or device operating to draw the air from the machine orinterior of its case, and, with suchair, all oating or detachedparticles ot' bronze, and to expel the same along a suitable pipe ortubular passage, either to pendent .canvasor other like bags, or intowater in which it will be precipitated, or suoli loose bronze may beotherwise collected after it has been drawn ott by the fan.

Referring to the accompanying drawinga tubular passage, C, which may dipat its outel end in water to collect the bronze by precipitation; but itis preferred to make this tubular passage of a cranelike form, and toattach to it, in a pendent and remov- Y able manner, at oritices b, madein its upper arm or portion, bags l), made of canvas, or other suitablematerial that will permit of the air drawn in by the fan passing ontthrough its interstices,V so as to prevent choking, but wili not allowot' the bronze escaping through it.

In this way, the surplus or float-ing bronze is deposited by itsgravit-y, and collected in the bags as it is passed by the suction-fanalong the tubular passage C.

A vacuum or suction being created within the case a of theln'onzing-machinc, and the fan B being supplied with air exclusively bythe necessary openings and cracks or joints in the case, all surplus ortloating bronze is passed by and th rough the suetion-fan to the bans orreceptaclearranged to'receive it.

Although reference here only has been made to bronze, the invention isequally applicable and' isdesigned to include the use of other materialsfor the like purpose, such as ultra-marine, Paris green, f ioek, andcrystallized glass, any of which may be worked in the bronzing-machine.

What is here claimed, and desired to be secured be Letters Patent, is-

1.. lhe combination ot'a suction-fan or device with a bronzing-machine,or the case inelosing the same, and a tubular passage connecting saidcase with a suitable receptacle or receptacles for collection of thetioating bronze, substantially as specified.

lhe combination of the bags D with the tubular passage C, the suotionanB, and the bronzing-machine A, or its case 1f, essentially as shown andde scribed.
